I have shown two control stations-one in the upper cabin, and indicated at 21, and one in the ower cabin, and indicated at 22,

Vat 23, 24, 25 and 26, I indicate ythe control cables operated from the control stations.

Communicating passages are provided be tween. the several cabins, andsuch passages are provided with ladders or stairs, such stairs being shown at 27, 28, 29 and 30; ladders however, be substituted.

I 4also provide a suitable landing gear, consisting of two double-wheel carriages, the carriage 31 being arranged at, or, near the forward end of the machine, and the carriage 3 32 being at, or near the aft end of the machine.

I will, of course, provide brakes for the wheels of the landin gear. Numerous windows are shown in ig. 1, but as these are 35 customarily provided, no reference will be made to them, and while I have shown only chairs in the cabins in Fig. 5, it will be understood that every convenience may be supplied, as will be warranted by the size and 4 general construction of the ship.

I desire it understood that the dimensions of all of the parts of my device may be varied at will, and other modifications may be made within the scope of the appended claims without departing from the principle or sacricing the advantages of this invention; it will, however, be noted that my device is made on a stream line and accepted dihedral is given the wings; that the wings are provided with a top camber, and may be provided with a bottom camber, if such is found desirable.

Having carefully and fully described my invention, what I claim and desire to secure by Letters Patent is In an airshi a body member having a plurality of ca ins associated therewith, the aft end of all cabins terminating at a sharp angle to receive the pressure of the back wash of air, a plurality of means for sup orting said ship 1n the air, and a plurality oi) means for driving said ship through the air, and a plurality of means for controlling said ship, all combined as herein specified.
